DESCRIPTION

FIG. 1 depicts an exemplary modular wall system 10 in accordance withthe present invention.

The modular wall system 10 may include a first vertical post 12, and asecond vertical post 14. Disposed between the first and second verticalposts is a screen (or flexible barrier material) 16. The screen 16 isset up on a roller system 18. The roller system 18 may be mounted in aframe 20 above the vertical posts. The frame 20 may be secured to astructure (not shown) above an opening in which the modular wall system10 is to be installed.

Referring to FIG. 2, the frame 20 may be formed from one or morecomponents, including a motor frame 22 and a center frame 24. The motorframe 22 may house a motor 26, a motor support arm 28, and one or moresupport arms 30. A plurality of rollers may be disposed between themotor support arm 28 and the adjacent support arm 30. The rollers may besteel rollers manufactured by Miller Bearing Company, Inc of Bromfield,Ohio. For example, as shown in FIG. 59, a pair of 1.375-inch diameterrollers 32 and one 0.75-inch diameter roller may be supported on one endby a motor support arm 28 and on the other end by a support arm 30.Additionally, each pair of adjacent support arms 30 may support a pairof 1.375-inch diameter rollers 32 and one 0.75-inch diameter roller 34.

Referring to FIGS. 3, 4, 5, 6 and 7, a description of structural memberswhich may form an exemplary motor weldment frame are presented in Table1 (below). Referring to FIG. 2, the length of the frame 20 may beincreased by connecting a center frame 24 to the motor frame 22. Forexample, a flange(s) 54 with one (or more) fastener hole(s) 56 on oneend of the motor frame 22 (see e.g., FIG. 3 and FIG. 5) may be bolted toan opposing flange(s) 54 and fastener hole(s) 56 on the center frame 24.In a similar manner, another center frame 24 may be fixed to the otherend of the center frame 24. Further still, a center frame 24 may bemeasured, cut to a desired length, and then secured to a preceding motorframe 22 (see e.g., FIG. 2) or a preceding center frame 24 to create acustom and intermediate length end frame 24. Accordingly, the length ofthe frame 20 may be determined by the number of modular sections ofcenter frames and end frames connected to the motor frame.

Although the motor frame 22 and center frame 54 may be weldment framesformed from square and rectangular members, as well as hot rolled steelbars, other structural shapes and members (e.g, channel, angle, T, I orother thin wall structural members) and joint construction may be usedto create a substantially rigid load bearing frame that may support andhouse components of a roll-up wall. Similarly, although the embodimentsof the structural members disclosed in Table 1 and Table 2 are formedfrom carbon steel, other metals, alloys, or other materials may be usedto modify or optimize engineering properties of the frame for a givenapplication. For example, a titanium alloy may be used to reduce weightand enhance strength of the frame to facilitate modular wall systemshaving increased tube lengths or multiple roller assemblies (see e.g.,FIGS. 66, 67, 68 and 69). In another example, a corrosion resistantalloy may be selected for use in installations near the ocean.

Referring to FIG. 9, a motor support arm 28 may include a stem 90, aninterior bracket 92 and an exterior bracket 94. The stem may include afront end 96 and a rear end 98.

Referring to FIG. 11 and FIG. 12, the stem 90further may include a lower surface 102. Referring to FIG. 10, the stemmay include a front aperture 104 situated adjacent to the front end. Thefront aperture 104 may extend from the upper surface to the lowersurface. The stem may include a rear aperture 106 situated adjacent tothe rear end. The rear aperture may extend from the upper surface 100 tothe lower surface 102.

The interior bracket 92 may connect to the stem 90 on the port side (orleft side) of the motor support arm 28. Referring to FIG. 11, theinterior bracket 92 may be planar having a generally flat and smoothouter surface 108 and a generally flat and smooth inner surface 110. Theinner surface and outer surface of the interior bracket may besubstantially parallel to one another. The interior bracket 92 furthermay include three fastener receiving holes 112. Each fastener receivinghole 112 may extend from the inner surface to the outer surface. Asshown in FIG. 9, two fastener receiving holes may be aligned verticallyabove a generally square notch 114 located at the lower rear portion ofthe interior bracket 92. The other fastener receiving hole may include aweldment nut 115 on the outer surface 108. The interior bracket 92further may include three horizontally aligned spindle receiving bores116. One spindle receiving bore may be situated adjacent the front end96 of the stem. The other two spindle receiving bores 116 may bedisposed on opposite sides of a recessed profile segment 118. Therecessed profile segment 118 may extend below the adjacent spindlereceiving bores. The recessed profile segment 118 may be concave. One ormore of the spindle receiving bores 116 may possess a central axis andthe bore may define a cross-sectional area normal to the central axis ofthe bore. The cross-sectional area may be uniform along the centralaxis. The cross-sectional area may have a geometric shape. For example,one or more spindle receiving bores may each define a cross-sectionalarea having a hex shape. In another example, a spindle receiving boremay define a cross-sectional area having a circular shape. Although, thespindle receiving bores 116 shown in FIGS. 9, 10, 11 and 12 define across-sectional area having a circular shape or a hex shape, any shapemay be used provided that the bore securely holds a roller spindle 120(see e.g., FIG. 56).

The exterior bracket 94 may connect to the stem on the starboard side(or right side) of the motor support arm 28. Referring to FIG. 11, theexterior bracket 94 may be planar having a generally flat and smoothouter surface 122 and a generally flat and smooth inner surface 124. Theinner surface and outer surface of the exterior bracket may besubstantially parallel to one another. The exterior bracket 94 furthermay include three fastener receiving holes 126. Each fastener receivinghole 126 may extend from the inner surface 124 to the outer surface 122.As shown in FIG. 9, two fastener receiving holes may be alignedvertically above a generally square notch 128 located at the lower rearportion of the exterior bracket. Each of the two vertically alignedfastener receiving bores 126 may include a weldment nut 115 on the outersurface 122. The exterior bracket further may include another fastenerreceiving hole 126 located forward and above the pair of verticallyaligned fastener receiving holes. The fastener receiving holes 126 onthe exterior bracket 94 and the fastener receiving holes on the interiorbracket 92 may be aligned. Each respective pair of aligned fastenerreceiving holes may be used to hold and receive a fastener (e.g., a boltor rivet).

FIGS. 13, 14, 15, 16 and 17 show another embodiment of a motor armsupport 134 in which the interior bracket 92 includes a second plate 130that is fixed to the interior bracket. The second plate 130 may includetwo rear tabs 132. The rear tabs 132 may be planar. The rear tabs 132may be vertically aligned. The rear tabs 132 further may be disposedapproximately at a right angle to the inner surface 124 of the interiorbracket. Also, the stem 90 may be generally L-shaped. The stem 90 shownin FIGS. 13, 14, 15, 16 and 17 may be wider than the stem 90 shown inFIGS. 9, 10, 11 and 12. Due to the thicker interior bracket 92 and widerstem 90 of the motor arm support 134 shown in FIGS. 13, 14, 15, 16 and17, this embodiment may accommodate larger motors and heavier tubes thanthe motor arm support 28 shown in FIGS. 9, 10, 11 and 12. The motor armsupport 132 of FIGS. 13, 14, 15, 16 and 17 may be referred to as a widemotor arm support. Other features of the wide motor arm support 134generally are similar to the features of the motor arm support shown inFIGS. 9, 10, 11 and 12.

Referring to FIGS. 18, 19 and 20 and FIGS. 21, 22 and 23, the modularwall system 10 (see e.g.,

FIG. 2) may include an anti-rotation arm 88, 88′. In FIGS. 18, 19 and20, the anti-rotation arm 88 may be described as possessing a generallypaddle shape. By contrast, in FIGS. 21, 22 and 23, the anti-rotation arm88′ may be described as possessing a generally triangular shape. In bothembodiments, however, the anti-rotation arm 88, 88′ may include a plate136. The plate 136 may include a motor mounting side surface 138 and afastener receiving side surface 140. The plate 136 may include a framesecurement opening 142. The frame securement opening 142 may extend fromthe motor mounting side surface 138 to the fastener receiving sidesurface 140. The frame securement opening 142 may be elongated along alongitudinal axis 144. The longitudinal axis may be a line of symmetryfor the plate. Although the plate may possess reflectional symmetry, theplate may be asymmetric.

The plate further may include a plurality of motor fastener receivingholes 146. Although each of the disclosed motor fastener receiving holesdisclosed in FIGS. 18, 19 and 20 and FIGS. 21, 22 and 23 are countersunk holes, other hole configurations may be used. For example, themotor fastener receiving hole may be a counter bore hole. Moreover, themotor fastener receiving holes may form a plurality of bolt patterns.For example, the two motor fastener receiving holes 146 that arebisected by the longitudinal axis 144 may be used to secure the plate136 to one motor; whereas, the four motor fastener receiving holeshaving a diameter great than the other motor fastener receiving holesmay be used to secure another motor to the plate 136. Hence, one boltpattern may require two motor fastener receiving holes, and another boltpattern may require four motor fastener receiving holes.

Preferably, the anti-rotation arm 88, 88′ may be formed from carbonsteel, although other metals and metal alloys may be used
